摘要: A composition for dental use containing a polymerizable monomer (a) having an aromatic ring and a hydroxyl group, a polymerizable monomer (b) having an aromatic ring without having any hydroxyl groups, and a polymerizable monomer (c) other than the polymerizable monomers (a) and (b), wherein the composition for dental use contains the polymerizable monomers (a), (b), and (c) in an amount of from 10 to 30% by weight, from 50 to 70% by weight, and from 10 to 30% by weight, respectively, of all the polymerizable monomers. The composition for dental use of the present invention can be suitably used as a product capable of substituting a part or all of a natural tooth in the field of dental therapy.

摘要: A cartridge-type dispenser has a cartridge main body with a filling space, an extrusion nozzle on the front, and a piston slidably disposed in the filling space. The piston extrudes contents of the filling space from the extrusion nozzle by applying a push-in force. The piston includes a trunk portion having an outer circumferential wall running along an inner wall of the main body with a gap therebetween, a front wall on one end of the trunk portion directly contacting the contents of the filling space, and a rear wall on the other end whereon a rod of a push-in tool applies the push-in force on the piston. On the outer circumferential wall of the trunk portion, protrusions are provided, which contact the inner circumferential wall of the main body. The points of contact form sliding parts of the piston but do not seal the main body interior.
